I love Cosette by Violette Field Threads for it's versatility. With an elasticized bodice and tie back flutters, it's fit is flexible and forgiving. It is also designed to create knee length or maxi length dresses with a plain or pleated bodice.
To create the apron, the fabric cut chart from the Magnolia Apron, also by Violette Field Threads was used. However, instead of cutting an apron skirt, a vintage pillow case was used.
The colors in the vintage apron were used as inspiration for the main fabric. Upon finding this yellow polka dot fabric, it was that it was a match made in heaven! Not only matching color wise, but the polka dots paid homage to the sun in the "You are my sunshine" song. In addition, the fabric and used for the flutters also featured a circular floral pattern.
The top of the vintage pillow case was used for hand embroidery of the phrase "you are my sunshine" so that they would be an exact match.
